OBJECTIVE: To report metacarpal fracture repair in a bull. STUDY DESIGN: Clinical report. ANIMALS: Simmental bull (n = 1; 870 kg). METHODS: A comminuted right metacarpal fracture was repaired using 2 transfixation pins (6 mm diameter) through the distal metaphysis and diaphysis of the radius and a full limb synthetic resin cast. RESULTS: Slight bending of both pins occurred 1 day after surgery. Both pins were loose and removed at 31 days and a full‐limb cast reapplied. The cast was changed at approximately −4 week intervals. On day 50, the right carpus had moderate overextension and a valgus deformity. An exercise program was started on day 62, and on day 110, the cast was replaced with a Robert‐Jones‐bandage. At 130 days there was circumferential callus formation and the bull was discharged. At 6.5 months, overextension of the right carpus had resolved and carpal valgus had improved. The bull returned to at 7.5 months after surgery, and was successfully used for 4 years. CONCLUSION: For highly valuable cattle like this breeding bull, a surgical treatment of such a fracture should be attempted despite a primarily poor prognosis.
